HAND FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 762,382, dated June 14, 1904.

Application filed March 3, 1904.

To all whom it may concern.-

Be it known that I, HENRY L. BURT, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraslia, have invented certain new and useful Improvements in Hand Fire-Extinguishers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improved hand fire-extinguisher for use in throwing a powdered chemical compound upon an incipient fire to extinguish the same by developing gases which deprive the fire of oxygen.

The object of my invention is to provide hand fire-extinguishers of this class with means for regulating the discharge of the powdered chemical compound therefrom and for spreading the said compound as the same is thrown from the extinguisher, so as to apply it efiiciently to the fire.

In the accompanying drawings, Figure 1 is an elevation, partly in section, of a hand fireextinguisher embodying my improvements. Fig. 2 is a transverse sectional view of the same, taken on the plane indicated by the line a a of Fig. 1.

The tube 1, which contains the fire-extinguishing powdered compound, is of the usual form, has the opening 2 in its upper end, provided with a detachable closure 3, and the said closurehas a link 4 hinged thereto, which enables the extinguisher to be suspended from a nfiil or similar object that projects from the wa In the embodiment of my invention I provide a regulator 5, which is here shownas in the form of an inverted conical-coiled spring which is fitted in the upper end of the tube and depends from the top thereof. The lower end of the spring-regulator is bent angularly,

Serial No. 196,342. (No model.)

' as at 6. The coils of the spring-regulator retard the discharge of the powdered chemical compound as the same is thrown from the tube when the closure has been removed, and, moreover, the said coils serve to spread the compound as it is thrown from the tube and enable it to be evenly distributed into the fire. The spring-coil holds itself in place in the tube by frictional engagement with the side thereof.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without rcquiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described myinvention, what I claim as new and desire to secure by Letters Patent, is

A hand fire-extinguisher comprising a vessel adapted to contain a powdered chemical compound and having an opening and a closure therefor, and a regulator to spread the material as it is thrown from the vessel through the opening, said regulator comprising a spring-coil of inverted conical form, said spring-coil engaging the inner side of the vessel and thereby retaining itself in place and being disposed opposite the discharge-opening of the vessel, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HENRY L. BURT.
